1987年12月11日至4日在沪东造船厂召开了垂直气电自动焊工艺的鉴定会,会议由中船总公司技术部主持。该工艺采用 SG-2型焊接装置,焊接板厚为14～25mm 厚的垂直对接缝。其工艺稳定会,可靠、焊缝成形美观、质量易保证,适宜在大,中型船舶的船台大合拢等平直部分进行垂直接缝的焊接。这种垂直气电自动焊工 From December 11 to December 4, 1987, an appraisal meeting of the vertical automatic gas welding technology was held at the Hudong Shipyard. The meeting was presided over by the technical department of CSSC. The process uses SG-2-type welding device, the welding thickness of 14 ~ 25mm thick vertical butt joints. The process will be stable, reliable, beautiful weld formation, easy to ensure quality, suitable for large and medium-sized ship slipway large straight part of the vertical seam welding. This vertical gas automatic welder
